Fluid accumulation and adhesion after shoulder injury can be improved through shoulder warming, medication, physical therapy, surgery and other methods. 1. Shoulder warmth: As the blood circulation of the surrounding tissues will be impaired after a fall, in order to improve the blood condition around the shoulder, it is necessary to pay attention to shoulder warmth, avoid catching cold, and take proper rest at the same time. 2. Medication: non-steroidal anti-inflammatory drugs such as ibuprofen and diclofenac sodium can be taken to relieve the local inflammatory reaction of the shoulder, and then relieve the fluid accumulation and adhesion. 3. Physiotherapy: infrared laser therapy, magnetic therapy, intermediate frequency electrical stimulation therapy and other physiotherapy can be carried out at the position of shoulder joint to promote local blood circulation of shoulder joint, accelerate the metabolism of inflammatory substances and reduce the fluid and adhesion. 4. Surgery: If the condition of shoulder effusion and adhesion remains unchanged after physical therapy and medication, surgery is needed. There are many ways to improve the fluid and adhesion after shoulder injury, and it is recommended to go to the hospital for standardized treatment.
